Specification of Letters Patent.

Patented May 14, 1918.

Application filed December 29, 1917. Serial No. 209,524.

To all whom it may concern:

Be it known that I, JOHN MAYER, of the city of Hamilton, in the countyof Wentworth, in the Province of Ontario, Canada, have invented certainnew and useful Improvements in Linemens Ring-Pliers, of which thefollowing is the specification.

My invention relates to improvements in linemens ring pliers and theobject of the invention is to devise a simple tool by which a linemanmay easily, quickly and firmly clamp the rings to the messenger wire andat the same time provide simple means by which such rings may be easily,quickly and accurately spaced apart upon such wire prior to their beingclamped in position and it consists essentially of the followingarrangement and construction of parts as hereinafter more particularlyexplained.

Figure l is a general perspective view showing my tool in position readyfor clamping a ring in place upon the messenger wire.

Fig. 2 is a similar view to Fig. 1, showing the tool in the clampingposition with the ring clamped upon the messenger wire.

In the drawings like letters of reference indicate corresponding partsin the various figures.

1 indicates a messenger wire upon which the rings 2 are secured, suchrings being provided for supportingthe telephone cable. The rings 2 aresplit rings provided with up wardly extending hook-like portions 3 and 4arranged in alinement so that the messenger wire 1 passes through thesereversely set hook-like portions.

It has been found very diflicult in practice to clamp these rings inposition so that they will always be held firmly in place. In order toovercome this diiliculty I have provided the following tool, theconstruction of which I will now describe.

5 and 6 indicate a pair of lever arms, the upper ends of which arecurved inwardly at 7 and 8 and downwardly so as to overlap one another,the overlapping portions being reduced in thickness as at 7". 9indicates a pivot bolt which extends through such overlapping portionsin proximity to the lower end thereof, the portions through which suchbolt extends being preferably thickened at 9*. 10 and 11 indicate jawshaving semi-circular gripping portions 12 and 13, the jaws being widenedout in opposite directions at 10 and 11 to the full width of the leverarms 5 and 6.

By this construction it will be seen that I have provided a tool whichwill have a great leverage and which, when brought into contact with thehook portions 3 and I, will force them around the messenger wire so thatthey will grip it tightly in such a way that there will be nopossibility of the ring slipping longitudinally of the wire.

14 indicates an orifice formed in one of the lever arms 5 or 6. 15indicates a measuring wire, which extends at one end through suchorifice 1a and is secured there in by a clamping screw 16. It willtherefore, be seen that when one ring is clamped in position the freeend of the wire 15 is placed against such ring, the position of the toolsecured to the opposite end of the wire by the bolt 16 being so locatedas to gage the position ir which the next ring should be located uponthe messenger wire 1.

From this description it will be seen that I have devised a very simpleform of tool by which the supporting rings may be easily, and quicklylocated and secured in position upon a messenger wire so that there willbe no danger of their slipping from their position.

I am aware that other forms of pliers have been used before but no plierhas yet been devised as far as applicant knows which will providesufficient leverage to insure that the hook portions of the ring areclamped so tightly around the wire that no slip will occur. Furthermoreno tool has yet been devised which will provide means for spacing therings accurately an equal distance apart upon the messenger wire.

What I claim as my invention is:

A linemans ring plier comprising two similar elements each substantiallysemicardioid in shape and having a handle at one end and a jaw at theother, a pivot securing the elements together between the handles andthe jaws but being located above the jaws and the handles.
